Description

Plug-in magnetic force lock and keyboard

The utility model belongs to lock technology field, in particular a kind of plug-in magnetic force lock and keyboard.

At present, the employed common lock majority of people is that multiple tooth key is injected in the keyhole, rotates a circle then or a few Zhou Caineng opens.Many numerous and diverse parts have been added in order to increase function, for example:, be difficult to prevent that the people in the door from just can open the door away without key for anti-people has outdoors unblanked to add the knob on the door lock or operates a switch.Some lock, lock outwardly and is easy to as long as can lock door once being with without key, and reality has but been brought many unnecessary troubles, as: key drops on outdoors and has just entered house on the keyhole after opening the door; Firm going out, wind has blowed door, and key has dropped in the room, is difficult to into.For a little locks use not too conveniently, theftproof performance is also poor.Even advanced also all is the turnover panel of electromagnetic lock such as coded lock, Fingerprint Lock, IC card lock, retina lock, audio frequency lock etc. now, have only power connection just can open, in case power supply is interrupted, just can't open.Simultaneously, because complex structure breaks down easily, the cost height makes the ordinary people to accept.

The purpose of this utility model provide a kind of simple in structure, easy to manufacture, easy to use, cost is low, the plug-in magnetic force of security insurance lock and keyboard, to overcome the defective that prior art exists.

The technical solution of the utility model is achieved in that it comprises lock housing, main dead bolt, grid spacer, cylinder lever connecting rod, locking pin and main dead bolt return spring, it is characterized in that: cylinder lever connecting rod passes the magnetic force arm-tie that grid spacer connects main dead bolt and has permanent magnets, main dead bolt return spring is located between main dead bolt and the grid spacer and is enclosed within on the cylinder lever connecting rod, the side of lock housing flexibly connects secondary dead bolt, and secondary dead bolt return spring is set between secondary dead bolt and the lock housing.

Locking matching used keyboard with plug-in magnetic force is characterised in that: an end of keyboard be provided with the magnetic force lock case of lock in the opposite polarity permanent magnets of permanent magnets on the magnetic force arm-tie, the center has anti-Kai Changkai locating hole.

Good effect of the present utility model is: simple in structure, easy to manufacture, easy to use, low price, security insurance.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model unlocking condition;

Fig. 3 is the structural representation of keyboard of the present utility model.

Below in conjunction with drawings and Examples the utility model is described in detail.

With reference to Fig. 1, Fig. 2 and Fig. 3, cylinder lever connecting rod 4 passes hole on the grid spacer 5 by main dead bolt 2 and the magnetic force arm-tie 6 of being threaded, magnetic force arm-tie 6 is fixed on lock housing 1 inwall, grid spacer 5 usefulness screws 11 are fixing with lock housing 1, main dead bolt return spring 3 is located between main dead bolt 2 and the grid spacer 5 and is enclosed within on the cylinder lever connecting rod 4, secondary dead bolt 14 be fixed on by rotating shaft screw 12 on the side of lock housing 1 and and main dead bolt 2 be synchronized with the movement, the corresponding opposite permanent magnets of magnetic 10 that is provided with on magnetic force arm-tie 6 and the keyboard 7, between secondary dead bolt 14 and the lock housing 1 secondary dead bolt return spring 13 is set, the 8th, locking pin, the 9th, anti-Kai Changkai positioning seat hole.

Only need pull out when the utility model uses and to open lock or lock lock once slotting one, promptly no matter you are in will enter house outdoors, still from walking out within doors outdoors, only need an end of the no permanent magnets of the keyboard 7 that has permanent magnets 10 is injected in the keyhole, since on the keyboard 7 polarity of permanent magnets just in time with magnetic force arm-tie 6 on the polarity of permanent magnets opposite, so, keyboard 7 has just been inhaled, simultaneously, magnetic force arm-tie 6 has also been inhaled comes, cylinder lever connecting rod 4 overcomes the elastic force of main dead bolt return spring 3 pulls out main dead bolt 2 in lockhole, secondary dead bolt 14 also rebounds under the effect of secondary dead bolt return spring 13 in the lock housing 1, and this moment, door was opened.When opening that door enters within doors or when walking out outdoors, only needing close tight with the handgrip door, pull up keyboard 7 smoothly, door has just been locked again tightly.

For antitheft, the utility model design has increased a secondary dead bolt 14, and this secondary dead bolt 12 has played the effect of reinforcing main dead bolt 2, has more played the effect of the anti-saw of anti-sledge.After locking the door, secondary dead bolt 14 just in time keeps off between the lock and the crack between a door and its frame of lockhole, and can not about, move forward and backward.

For preventing that the human key opens the door outdoors, the utility model is provided with locking pin 8 outside lock housing 1.When you do not want to allow outdoors human key open, you only need keyboard 7 is not injected in the keyhole with an end of permanent magnets, pierce into 15 li of anti-Kai Changkai locating holes corresponding with it on the keyboard 7 with locking pin 8 again by the anti-Kai Changkai positioning seat hole 9 on the lock housing 1 then, so, do not advance in the keyhole though people outdoors has key also to insert, so the lock of not opening, prevent that keyboard 7 is stolen after losing.
